Bonded Sealing Washers

Sealing Washers have a layer of Neoprene bonded to the metal washer that forms a seal that is strong while also being soft and resilient. They can be used with fragile materials and to provide extra cushioning under a nut or the head of a bolt or screw. They are effective in stopping leaks by sealing joints. Washer size refers to its nominal hole size and is based on screw size. Its outside diameter (OD) is always larger.
